Sandbox testing is the practice of running software within an isolated, controlled environment designed to resemble production while remaining detached from live systems. The sandbox prevents changes or defects from impacting real users, data, or infrastructure and allows testers to observe behavior under safe conditions.

The primary purpose is to validate functionality, security, and reliability without risking production assets. Sandboxes are used to test new features, integrations, configuration changes, and risk-prone scenarios. They also support experimentation, debugging, and training without affecting end users.

Environment and setup commonly involve virtual machines, containers, or cloud-based sandbox environments. Data used in sandboxes is typically synthetic or masked to protect privacy. Network access, storage, and external service connections are tightly controlled, with comprehensive monitoring and audit logging to reproduce issues.

Testing activities in a sandbox may include functional and regression testing, integration testing with mocked services, performance and load testing, security assessments, and upgrade or rollback scenarios. Continuous integration pipelines often spin up sandboxes for isolated builds, enabling repeatable, automated testing.

Types of sandboxes include developer sandboxes, QA sandboxes, and security sandboxes, each serving different stakeholders and objectives. While sandboxes improve safety and reproducibility, they may not perfectly mirror production due to data gaps or environmental differences, and they require maintenance and cost management.

Best practices emphasize using representative or masked data, ensuring network isolation, automated provisioning and teardown, version-controlled environment configurations, and thorough monitoring. Sandboxing is related to test environments, feature flags, and security testing methodologies.
